SAN DIEGO, May 3 /PRNewswire/ -- Naviscan PET Systems, Inc., a privately held company specializing in the development of high-resolution PET scanners, announced today that it has completed a $15 million Series C round of financing. The financing was led by QuestMark Partners of Baltimore and joined by Sanderling Ventures, Mayo Medical Ventures and Walker Ventures, all previous investors in Naviscan. Michael Ward, a partner at QuestMark, will join Naviscan's board of directors.

Proceeds from the financing will be used to further clinically validate and commercialize the PEM Flex(TM) Solo II PET scanner, Naviscan's patented high resolution PET scanner. The company also plans to use the proceeds to continue development of other imaging and intervention technology, including proprietary imaging agents.

Naviscan PET Systems is the first company to obtain FDA clearance of a high-resolution PET scanner designed to image small body parts. The device was developed to help physicians and researchers diagnose and locate cancer, guide interventions and advance new clinical therapies.

"The PEM Flex(TM) Solo II PET scanner provides unprecedented clarity and resolution, allowing physicians to image tumors less than 2 millimeters in size," said Paul Grayson, President, Chairman and CEO of Naviscan. "It is the difference between seeing and not seeing the tumor, meaning early detection and the potential for more cures."

"Naviscan's PEM technology represents a significant step forward in the field of imaging and breast cancer," Ward said. "We wanted to support Naviscan's commercialization and product development efforts because we believe the product's superior resolution, sensitivity and specificity may improve patient care and lead to better outcomes."
